Application filed October 10, 1883. Serial No. 108,573. (No model.)

To all whom it may concern:

Be it known that 1,. ROBERT P. GARSED, a citizen of the United States,residing at Norristown, in the county of Montgomery, State ofPennsylvania, have invented a new and useful Improvement in Pumps, whichimprovement is fully set forth in the following specification andaccompanying drawings, in which;

Figu ife 1 is a partial vertical section and side elevation of a pump'embodying my in-' vention. Figs. 2,3,4, 7, and 8 are side elevations ofdetached portionsthereof. Fig. 5 is a top or plan View of the righthandportion of Fig. 1. Fig. 6 is a bottom plan ofthe pump-barrel. Fig. 9 isa vertical sectionof an inflatable body employed. Figs. 10 and 11 arevertical sections of modifications.

Similar lettersof reference indicate corresponding parts in the severalfigures.

My invention consists of a pump of novel and inexpensive construction,the same being easily operated, occupying small space, and possessingother advantages, as will be hereinafter fully set forth.

Referring to the drawings, A represents a casing or cylinder, formed ofsuitable metal, and sustaining within it the pump-barrel B, formed ofrubber or other flexible material. The upper end of said barrel, at thecenter thereof, is bulged upwardly, as at C, said bulge protrudingthrough the opening at the top of the casing A, and to the said bulge issecured a handle or push, D, which is adapted to pass through the saidopening at the top of the casing, and made of tubular or skeleton form,corresponding with the shape of the bulge at the top of the barrel. Onthe inner face of said bulge is fitted a cap, E, which coincides withsaid inner face of the bulge, and has bearing against it the upper endof a spring, F, which is inclosed in the barrel and has it base restingon the bottom G thereof. In the bottom G of the barrel is a tube orpassage, H, which also passes through the bottom of the casing A,wherebythe fluid may be admitted to or discharged from the barrel, the outerend of said passage having connected with it a tube or pipe, J, which isin communication with a bellows or inflatable body,

K. The inner or upper end of said passage H, which is within the barrelis formed with or has secured to it a perforated head or button, L, forthe attachment of the bottom of the barrel, it being noticed that saidbottom is provided with a small aperture, so that when it is stretchedthe aperture enlarges sufficiently to pass over the head, and whenallowed to contract it closes around said head and forms a tight jointbetweenthe parts, and also holds the bottom of the barrel on the bottomof the casing, it also being seen that the spring F-is of conical form,so that when its coils are compressed they close around the head orbutton without obstructing the bore of the passage H, and fold so as tolie one within the other and occupy a vertical space equal to the heightof said button, thus occasioning economy in the length of the spring andheight of the pump.

On the inner face of the casing, near the bottom thereof, is anannularbead or shoulder, a, against the lower edge whereof abuts thebottom G of the casing, and in order to prevent downward displacement ofsaid bottom the lower end of the casing is formed with clips M, whichare bent up under the bottom G and serve to sustain the same. In Fig. 10the bottom rests on the clips or a flange on the lower edge of thecasing, and the passage H is threaded to engage with a disk or spider,N, whereby said bottom and disk or spider may be screwed together andthe bottom tightly clamped in position.

In Fig. 11 the head or button is movably connected in position, so as toadjust the same relatively to the thickness of the coils of the springF, and for other purposes requiring such adjustment. The bottom of thebarrel has secured to it a disk or piece, 1?, of rubber or othersuitable material for re-enforc-ing the same.

In Fig. 10 the bulge is elongated, and has its upper end fastened to thehandle or push of the pump, and a spring encircles the barrel, the sameresting on the bottom of the casing and bearing against the lower end ofthe handle or push D, the cap E being unnecessary.

If desired, a small orifice may be made in the top of the barrel toadmit air thereinto, said orifice being closed by the cap E when thebarrel is being depressed.

It will be seen that by depressing the handle or push D the barrel iscompressed, whereby the fluid is forced through the pipe J to the bodyK, thus inflating the latter and moving the head thereof in onedirection. The bulge O and form of the handle or push D, which encirclessaid bulge, prevent the top of the barrel striking the head L, thusguarding the same from injury. When the handle or push is let go, thespring restores the barrel to its normal con dition and the fluid iswithdrawn from the body K, thus contracting the latter and impartingmotion to the head in the reverse direction. The reciprocating motionsof the head are availed of for various purposes, such as the operationof a bell ringing device, wherein thehammer is actuated by mechanism towhich motion is imparted by a pinion with which engages a rack attachedto the head.

The bellows K is made of sections riveted together, wherebyI may employfor the same stiffer, tougher, and stronger material than when made inthe ordinary Way.

I f desired, the pump-barrel may be made of bellows form withevenly-collapsing folds.

Having thus described my invention, what I claim as new,and desire'tosecure by Letters Patent, 1's- 1. A flexible pump having a bulged head,in combination with a casing, a tapering spiral spring contained in saidpump, a button inserted within the barrel of said pump and retainingsaid pump in place, and a plunger working toward said button, saidplunger and button being adapted to fit one within the other,substantially as set forth.

' 2. A pump-casing havinga perforate button inserted in the bottomthereof, in combination with a pump-barrel, the said perforate buttonbeing alsoinserted in the bottom of the, said pump-barrel, a plungerhavingabulgedhead, the base of the said head being of greater diameterthan the said button, and a pipe connected to said button, substantiallyas and for the purpose set forth.

3. The pipe J and bellows K, in combination with a button, L, providedwith a passage communicating with said pipe J, a casing, a pump-barrelwithin which said button eX- tends, a plunger, and a spring containedwithin said barrel, substantially as described.

4. A pump-casing having an openingin its top, in combination with abarrel having a bulged head fitting said opening, a handle attached tosaid barrel, and a rounded button securing said barrel to said casing.substantially as described.

5. A flexible pump-barre1 having a rounded or bulged head, a plungerconstructed to fit said head, a spring contained within said barrel, acasing inclosing said barrel, and an outlet and ,inlet pipecommunicating with the interior of said casing, substantially as setforth.
